"WebSep 12, 2024 · The units of RC are seconds, units of time. This quantity is known as the time constant: τ = RC. At time t = τ = RC, the charge equal to 1 − e − 1 = 1 − 0.368 = 0.632 of the maximum charge Q = Cϵ. Notice that the time rate change of the charge is the slope at a point of the charge versus time plot. " - Tau meaning physics
